JB’s American made brass SAE 45° flared tube fittings may be used with copper, brass, aluminum, steel, and plastic tube provided an acceptable fl are could be generated with the material.
Vacuum and pressures of 5,000 psi can be handled depending upon the size, material, and conditions. Using a 4:1 safety factor, the following general rule (excluding plastic tube) is used:
- 3,000 psi to ¼"
- 2,000 psi to ½"
- 1,500 psi to 1"
Long nuts are recommended when vibration is a factor. Tubing should be double flared in extreme applications to minimize fl are thinning on over-tightening.
Fittings listed generally comply with SAE, ASA, ASME, and MS standards; however, when design makes dimensions critical, please contact us at 800.323.0811 for samples and/or prints for testing and evaluation.
Tube sizes listed are OD (outside diameter). To determine nominal (water tube) size, subtract 1/8", thus 5/8" OD equals 1/2" nominal.
Pipe sizes listed are standard nominal pipe size and threads are to Dryseal Taper Pipe Standards.
JB will provide flare fitting to SAE Standard J513 whenever possible. In some cases, slight deviations will occur when full compliance fittings are not available.
- Make and break
- Good vibration resistance (improved by using long nuts)
- Low cost
- Easy assembly
- Wide selection
Heavy-duty ACR tube fittings generally conform to SAE, ASA, and ARI Standards for hydraulic, marine, and refrigeration service. Long dryseal pipe threads minimize leakage and provide more clearance for tightening flare
nuts. Shapes, elbows, tees, etc., are made from brass forgings to maximize strength and eliminate cracks.
